BUSHING TYPE VACUUM SWITCH

摘要

An electrical interrupter-bushing is depicted which provides a unitary cast envelope having end sealing members integrally cast with the envelope. The envelope is adapted to accommodate separable electrodes in hermetically sealed relationship within the bore of the glass-ceramic envelope. The lower portion of the envelope is adapted to extend within a cabinet and will accommodate a current transformer. Thus, a single unitary structure is provided which operates as an entrance bushing and as an interrupter envelope.
